PICVideo is a MJPEG codec which makes it possible to reduce frame size of almost half without visible quality loss. The video rate for a capture into VideoCD format (352x288, 16bits, 25fps) passes from 4500KB/s without compression to 2700KB/s ; it's perfect for IDE ATA66 7200rpm hard drive.
Although quality loss isn't visible, MJPEG compression artifacts aren't very well adapted to further calculations like MPEG-1 encoding ; in most case compared to Indeo and Huffyuv codecs.
For MPEG-2 (SVCD), it seems that this PICVideo is appropriate with few loss at Q=18 or Q=16 if you capture at 768x576 (or 768x480 for NTSC), compression ratio is up to 15:1 (Q=18) and 30:1 (Q=16). Let's take a look at SVCD capture testing I did.
It's downloadable from Pegasus Imaging at PICVideo Motion JPEG. Version 2 registration was free (PICVIDEO2), now it's $18 but worth it.
Once installed it will be accessible from most video editing software like Virtual DUB. With Studio, the PICVideo codec is not accessible for decoding but it is for encoding AVI.
With Virtual DUB, configured with a maximum quality (20), the video rate passes from 4500KB/s to 2700KB/s.
As it isn't recognized for decoding by Studio, it's then necessary
to convert AVI files with Virtual DUB by using the
and choosing Microsoft, Indeo, Huffyuv or Pinnacle (miro-XL) codec or uncompressed
